To all 207mm it may concerm,

I Be it known that I, FREDERICK W. COLE, acitizen of the United States,residing at NewtoniHighlands, in the county of Middlesex and State ofMassachusetts, have invented an Improvement in Successive Non-'Interference Signal-Boxes, of Which'the following is a specification.

This invention relates to fire-alarm tele.- grapli signal-boxes, andparticularly to that type commonly known as successive non-in- TheOrdinary box ot this type, when pulled, is arranged to send'.

terference signal-boxeswill be delayed fora short or a long perio oftime depending upon the conditions which caused the delay. There comes-a time after a boxhas been pulled that the transmission of its signalis absolutely use-` less, its reception being too late for the call ofthe tire apparatus, and in fact it had much better not then be sent forthe reason that it might cause delay in responding to some Theparticular broad characteristic feature of the box embodying thisinvention is its capability of lsendingits signal promptly, when the boxis pulled, and if for any reason its signal is delayed, then for sendingit promptly upon' the cessationfof the conditions Which caused its delaybut only Within a reasonable length of time, and restoring the componentparts to normal as soon as it has sent its signal or at the expirationof the 'period of time which is allotted for the sending. of the signal.

-While my invention is of abroad characf ter, and I do not wish to limitit to any particular structure, yet herein the abnormal extension oftime Within Which the signal may be properly sentis acquired by delayingthe action of thestopping-means for the sig-A naling-train, in caseanother signal is being sent over the line, or there'is trouble on theline,'whereuponthe signaling-train is permitted` to continue` itsoperation, but cannot send its signal, such delay beingfor a. period oftime which vvaries according to the conditions existing which caused thedelay, but-in no event will it be longer than a predetermined period ofamawhieh is auoaea during which a signal may besent, and at theexpiration of which 'period of time the stopping-means will operate tostop the train in any event andthe component parts of the .box Will thenbe restored .to normal preparatory to being again pulled.The'delaying-means for the ystopping-means. by which the train ispermitted to continue running,

` but only for a predetermined period of time,

may consist of means for disconnecting the stopping-means from thel'signaling-train,v

which is operable to thereafter connect ythe same thereivithzvthereby todelaythe'stopping of the'train, and subsequently to con-A 4nect the samewith the train, after Which it will operateto stopv the train When thetrain has run llong enough to send the predeter-l mined number of roundswhich itis designed tosend.` I Disconnection from the signaling-trainmay be controlled by the armature of the non-interference magnet, whichis'the elementresponsive tol anothersignal being sentfrom another box orAto trouble on the lineT and the subsequent connection of thestopping-means 'With lthe train consists of means adapted to be' opel#`ated or controlled by the train in running. Connection of thestopping-means With the train, after it has been disconnected thereofthe stopping-means.

from, Will be attempted repeatedly at reguy lar times, as for instance,lat the end of each v round of the signal during the time allotted forthe boxto run, and such attempts Will be .controlled.by the train inrunning, and `When lmade Will operate tostop the train after apredetermined number of roundsof the signal have been correctlytransmitted or the train hasrun for a corresponding period of time.v 4

` Of course, it Will be understood that yin v case there'is no othersignal being sent over 'the line or there is no trouble on the line thestoppingfmeans will not be' disconnected from the train and will operateto stop the train When the, predetermined number of will many timesresult in vdelaying the send-r i ing of the delayed signal only for alshort period of'time, which is a great advantage,4

is herein controlled by aV counting-device adapted to be operated by thetrain in running, being moved at the end of each round of the'Y signal,and when a predetermined number of rounds have been counted od', so tospeak, it operatesto prevent the armature from further controlling theconnection of the stopping-means with the signaling-train, which meansis then driven by the train, in regular manner, for a predeterminednumber of rounds whereupon it operates to stop the train Whether thedelayed signal is sent or not. The counting-device is adapted to bereturned to itsnormal position by a spring and is released to do so bythe stoppingmeans', thus providing for the return to normal of thecounting-device Whenever the train is stopped. |Thus in accordance Withthis invention,` as illustrated in the embodi-lv ment here shoivn,thedisconnecting means for the stopping-means is controlled bythenon-interference magnet to disconnect Said stopping-means from thesignaling-train; and connection of the stoppingmeans, with thesignaling-train, after it has been disconnected therefrom, is attemptedat the end of each round of the signal by.means cotrolled bythe traininv running, and connection of the Vstoppiiig-means with thesignaling-train after vit has been disconnected therefrom -is maintainedin any event at the 'end of a predetermined' number of rounds of thesignal by the counting-device which is adapted to be'operated by thesignaling.-` train in running to maintain 'sucliconnec.

tion, and isl adapted to be released by the stopping-means `When actingto stop the' f train toreturn tonormal.

Fig. 3 is a side elevation of the signalboX shown in Fig. vl.

Fig. 4 is a vertical, sectional detail of a portion of the boX.

F igs. 5 to 9 are fragmentary details of certain associated parts in thedifferent positions they-Will occupy during the ruiming of the train andunder different conditionsmounted to rotate on the stud 3.' A stopimember is secured to said pinion or other- Wisearranged'to rotate withit, which member is here shown as a disk 6 having a projection 7. A pin'8 projects iaterally from the'faoef ofthe toothed-gear a, .and,-as saidWinding-shaft rotates, passes through an orbit, and 'the projection 7 isarranged to enter the orbital path of said pin upon each 4revolution ofthe pinion, and is4 adapted to be engagedby'said pin to limit theWinding-motion of the shaft when the spring has been'tvound, thustoobviate Winding the spring overtight. The relative number of teeth onthe toothed-gear i and pinion are su'ch as to permit the toothedgear tomake several rotations before its pin encounters the projection 7,notwithstanding said yprojection passes through the' orbital path of thepin during each of these rotations.` The shaft is Wound by turning itcounter-clockwise and is rotated by the main spring in a clockwisedirection. There is also' mounted on the .Windingsliaft a spur-gear l0,whichl is adapted to be driven by the shaft, being connected therewithin any usual manner, as by a pawl 12, arranged on the gear 10, whichengages a ratchet-Wheel 13 secured to the shaft, so that the energy ofthe spring may beimparted to said gear. Said gear 10 en- Sts gages apinion 14, see Fig. a and dotted lines y Fig. 2, securedto a shaft`l,to' which the box-number signal-Wheel .16 ,is'rsecured A spur-gear20` is secured to or arrangedto rotate with the sigi'ial-ivlieel shaft,it being,

here shown as mounted upon and securedk tothe hub of the pinion it, andsaid gear 2O engagesa pinion 21, secured to a shaft 22, to which theescapement-Wheel-23 is secured, said wheel 23 being engaged by a pallet24, secured'toa pallet-shaft 25, bearing a" fan E26.Stripped'of*associated elements, to be hereinafterdcribed, 4thisytrainof gearing Y serves asrand constitutes the signaling-train. Thissignaling-train is adapted to be held vat rest against the energy of itsactuating` spring by stopping-means adapted to be v"controlled, by thebox-pull to start the train,

and to be operated by the train injrunning to stop thetrain. pingmeansis adapted to be disconnected from the train, to permit the train to runindependently thereof, in case the signal is delayed. The stopping-meanshere shown consists of a dislr 36, having a single notch 37, whichreceives the end-portion or tooth 38 of a locking lever 39, which issecured to a pivot-shaft 40, said notched disk, which serves as thestop-Wheel, being loosely mounted, for convenience, on the .Windingshaftl. Said'notched disk is .arranged to be driven by the Signalingftrain bymeans whereby it will make one rotation to-sev eral rotations, say four,of the signal-Wheel, L30 I Furthermore, the stopso Vthat in the normalrunning of the train,

several rounds of the signal, say foun -is engaged by a pinion 34,arranged for con# venience on the signalfwheel shaft 15, and

n yadapted for connection with the train.

Said pinion 34 is loosely supported on said shaft 15, and ,on its hub adisk is rigidly secured, having pivoted on its face,`

aty 32, a dog 31, one end of which has an engaging4portion arranged toengageand disengage a pin 50, which projects laterally from one of thetrain-wheels,` as 20, and the other end offwhichforms an vektensionortail 72, which may extend outward beyond the edge ofthe disk, see Fig.2, or may be otherwise arranged for engagement with means to cause it tobe moved von its pivot. By4 means of the pin 30'and dog 31,' thelstopping-means` is adapted to be connected 'with and disconnected fromthe train.

When the dog is in engagement with the pin, the stopping-meansisconnected with stop-wheel 36, and the dog 31l engages the pin 30, thesignaling-train is held at rest through the gear 35, pinion 34, disk 33,dog

V31, pin 30, and train-wheel 20; and when said locking-lever disengagessaid notch the signaling-trainv is permitted to run; and

when the dog 31 isomoved out of the path of movement. of the pin 30, thesignalingtrain' is permitted to run and the stopping-` `means, includingthe stop-wheel, is permitted to remain at rest.

The box-pull 41,.shown as a pivoted lever, is arranged beneath thelocking-member 39, by which said kmember may be lifted against thetension of its return-spring 12,

to disengage the notched disk 36, and there-l by release thesignaling-train.

The signal-key 45 is arranged to control the make and breakof a pair ofContact: pens 46, 117 by cooperating with the signal-` wlieel 16, ithaving a projection 51, arranged for engagement with the" toothededge-portion of the signal-wheel for the ac complishment of thisresult.It is pivoted at 48, and its movements to and'i fro are limited by vapin '49, which is extended laterally from it and' enters a hole 50 inthe frame, which hole"r is madelarger than the pin. It also has a pin52, arranged for engagement with a prop 53,. by which itis held in 'its.closed circuit position, but which, when said prop ris lifted, willpass beneathy the prop, so as to act to hold the prop in elevatedposition While said key is in its open position. The upper end-portionof the key vis arranged for cooperation with a pin 54, on thebox-controller, in such manner that each can at times control theother,` as will be observed. Itslower end-` portion has an extension 55which is a-rranged to-be engaged by a pin 56 onthe' locking-member 89,byv which it is restoredV -to normal or closed position when thelocking-member enters the not'ch of the stopwheel.

'The prop 5,3 is piyoted at one end, asat' `times by the prop, or theprop by the key.

The projectionY 61 isadapted for engagementwi a cam 63, which isarranged on' or rotatable with the signal-wheel. Thisl cam extendsentirely around or is oo-eXtensive with the signal-wheel 'and might bemade as a flangeon the wheel; and a portion thereof, which correspondswith the period between the end of one round and the beginning of thenekt round rof the signal, is cut away, or ,in lieu thereof a void maybe provided. Along the cut-away por-l tion' of the cam the vprop ispermittedat times to `move into its lowermost position, see Fig.` l, inwhich position its projection 6.0, engages or passes beneath the pin 52on the signal-key to act thereafter to hold or prop said key with itscontact-pens in closed position. l

The remaining portion yof the cam acts to lift and hold the prop highenough for its projection` 60 to move into a plane above Vthefpin .52,see Fig. 5, so as to admit of said V,pin passing beneath it. @When theprop is thus lifted by the cam, thesignal-key is free to moveA intothefinterdentalvspaces of thefsignal-wheel, unless otherwise held, andwhen so moved, see Fig. 6, its 'pin 52 will lpass beneath the projection60 on the prop,

and will act to hold said prop in elevated position, .so as to preventit from again falling into its cut-away portion,v i

When' the box is at rest, the projection 61 on the prop will be'disposed intermediate the length of the cut-away portion of the cam,andthe prop will then be in its lowerytemporarily be held from' openingwhile the notch inthe cam is passing and the signal-wheel will rotateand when its rst tooth .reachesthe key the cam will soon litt the propinto the position shown in Fig.`5,

thereby disengaging the signal-key, andthe 'reason that the prop is heldin eleva-ted position bythe cam, during the rotation of thesignal-ii'heel, and until the eut-away por-V tion arrives opposite thehroyectlon 61' thereof. rlhe cut-away portion of the cani is arrangedopposite the long interdental space of the signal-Wheel, which occursbetiveen and is designed to differentiate the rounds or the signal. Thesignal-key will be in its open position between the rounds of thesignal, and its pin 52 will then be disposed beneath the prop at thetime said prop arrives at thecut-aivay portion, so that the prop, willbe held in elevated position during the passing of said cut-awayportionby the signal-key, unless it should so happen that the signal-keyis held in or restored to closed position by other means, as, forinstance, by `'abnormal position of the boX controller or the returnmovement of the 'locking-.member to` normal at the "completion of analarm. A

The time consumed in movingthe signalivheel from the position shoivn inFig, l to the positionV showny in Fig. 5, to disenga'ge the signal-key,is of longer duration than the longestvclosure in any signal,'and it isv during `this time that the boX is placed under the control of thecircuit, as will be described, so that if another signal isbeingsentover the line, or there.: is troubleonthey line, the signal which isabout yto'be sent will be delayed.

The delay of the signal is Controlled by y f thenonfinterference magnet65, thearma- ,ture 66 of Which'is arranged on the lcontrollinglever 67,herein termed the' boxcontroller, which is pivoted `at 68.

A pin ,54 of cylindrical formation and slabbed'o on its underside isextended,v laterallyfrom the box-controller and norn attracted position,so that. While the signalkey is in open position the armaturewill beheld in its attracted position. Thus during holds. the signal-key initsclosed the signal will likewise be'delayed` A lAn attempt to sendthedelayedsignal'is subsequently made at each 4revolution lofftheit-iss? the normal operation of the box, in case the line is clear, thearmature Will be repeatedlyV held in its attracted position, when thecir-- cuit is opened by the-signal-lrey. In case the armatnureis orVshould be .retracted While the signaldrey is in its closed position?``then said pin 54 Will be vmoved to one side of the signal-key and intoits path of move.-

ment, and in such position Will act to prop` and thereby hold said keyin its closed position, until the armature is again moved intoitsattracted position, so that no signal Y can then be sent by said key,notwithstanding the train is running.

In case another signal Ais being sent over the line, or there is troubleon the line, the

non-interference magnet lwill respond to Ysuch condition du'ringtheprolonged period of time Which follows the pulling of the box andprecedes the first opening of the signalkey, and will 'move thepin 54:into position r to hold the signalkey in its closed position,

notwithstanding the signaling-train is 'run ning `and the prop has beenproperly moved into its disengaging position,`thus the sendingof thesignal Will be delayed.

After the armature is moved into its `retracted position for the purposeofcausing the signal to be delayed the stopping-means will bedisconnected from the signalingtrain.

As a means for accomplishing this result,

troller, which, when the armature is retracted, is moved into the pathof movement Y of the tail 72 of the dog '31, so that upon engagementvthereivtih said dogwill be 4moved to disengage the pin 30, as shown inFig. 8. Said pin 30 then continues its or-' bital movement v vith thevtrain-Wheel 20, and the train continues to run', but the stopping-meansis disconnectedfrom the tra-in and remains at rest, and, as' theboa-controller When thus retracted-also engages and position,

be started. For. the accomplishment of thisA result apin 7 5 is arranged,on one'ofvthe train-wheels, as 2O for' instance, which wheel. it willbe noted, is secured to the sig:

nal-wheel shaft, and' during each rotation of said Wheel, said pinpasses a lprojection 76'on the box-controller, as shown in Fig. 2.

.Said pin however normally occupiesthisy l position opposite saidprojection.V

When the armature is inits retracted position, as it will be While thesignal is being delayed, said pi-n in its orbital movement `'Will engagesaid projection 6 andfmechanically move the box-controller and armatureinto attracted position. This Willfbe done n during the time the notchin,-cam.63 isbe- 'neath the projection 61 on the propl and,-`

While said prop is in its propping position, Which it assumed instantlythe notch passes Abeneath it, as the key itself, on account `ofretraction of the armature, was then heldin closed position by saidretracted armature.

After the restoring pinf 5 passes the proj ection 76 on thebox-controller, said controller Will thenv be left under control of themagv net until the lirst tooth of the signal-Wheel passes beneath thesignal-keyY as Was the case When theboxvvas iirst pulled, The period oftime elapsing While the armature is' thus leftv under control of itsmagnet and before'the key can thereafter open the circuit is longer thanany closure in a Signal and vif the circuit remains continuously closedduring this period, it indicates that; no signal is then'usmg the line,and the key` is then free tolbegin its signal. In case the armature isnot held bythe non-interference magnet during the Whole of thistime,then it will again resume its retracted positionto again lockthekey during the succeeding whereupon thetrain will then engage and drivethe. stopping-means until the notch of the disk 36 arrives in positionfor reengagement of the 4locking-member 39, and the train willbestopped. In case the line Was not free of other signals or incondition to send the attempted signal up to such time then thedelayed'signal will notbe sent.

For the accomplishment of these results.

a .counting-device is provided, adapted to be moved one step for eachround of the signal, or for each attemptto send a round of the signal,Which,v as here shown, comprises a mutilated ratchet-wheel 80, having aseries of teeth adapted to be successively 'engaged by the aforesaid`pin 75, on the train-Wheel 20, or by other means operated by thesignaling-train on or at the end of each round of the signal, to move'it intermittingly, andV having asingle long tooth 8l, also adapted to beengaged by said pin 75, and having next said long tooth a void orinterdental space. Said ratchet-Wheel is mounted loosely, forconvenience, on .the

Winding-shaft, and it has a circumferen- I tially grooved hub 83;*and aspring 84 is attached at one end to' the'Wheel, and at the other end toa pivoted member 85, or it may be to some other point. This spring isarranged to be Wound upon said hub, in the groove thereof, as theratchet-Wheely is intermittingly rotated, `and is employed to return theratchet-wheel to its normal position, when so ypermitted to act'. A

. The member 85 1s designed lto serve as a l stop to hold theratchet-Wheel in its normal position, as shownby dotted lines Fig. 2,

and also as a pawl to hold the ratchet- Wheel in any of its intermediatepositions. This member is pivoted at 86, and has a nose 100, arrangedfor engagem'entwith the long tooth 8l, and has a projection 89, ar-,Vranged for engagement with the teeth of the ratchet-Wheel. Said member85 is movable ony its pivot into and out of co-active relation withtheteeth of the ratchet-Wheel, and I' normally is so held that itsprojection 89 is out of the path of movement of the short ratchet-teeth.To move thisv member a long slot 87, is formed in it which receives aprojection on a member 88, lwhich is secured to the shaft of thelocking-member,

so'that upon a lifting movement of the locking-member said member 88 maybe correspondingly lifted. Thel Slot 87 in lever 85 is -so shaped thatWhen member 88 islifted the member 86 ,can move intov the position shownin Fig. 7, whereupon its projection 89 will be inposition for co-actionwith the teeth of the ratchet-Wheel, but when the` locking-lever dropsit will again raise lever 85. Tlie'spring 84' being attached to saidn'ember 85 serves to yieldingly hold it in s lengagement with theratchet-teeth, permitting it to'yield'as the ,teeth of the ratchet-Wheel pass the, projection 89.

Thus it will be seen that the co-active relation of the components ofthe countingdevice are controlled by the looking-member,

which forms a component part of the`stop p ping-means, and thecounting-device Will be active during the time the signaling-trainv yisrunning.

During the running of the train, and at the end of each`round-v of thesignal, the I pin 75, willengage and move the ratchetwheel 80 one step,and said Wheel will be held bythe member 85, but as soon as thestopping-,means resumes its normalor stopping position and itslocking-member enters the notch of the stop-Wheel, themember` 85' willbe returned to its normal position, and having thus disengaged theratchet-Wheel said ratchet-Wheel is permitted to resume its normalposition by the action of the spring 84.

In case the line is free, and the stoppingmeans admits of, say,` fourrounds of the signal being sent, the only function subserved by thecounting-device Will be vthose above-described.4 In case, however, theline' is not free and the signal is delayed, and the stopping-means'is-disconnected yfrom the sig- Y naling-train, then the' ratchet-'Wheelvvillibe successively advanced step by stepfor a pren determined numberof rounds of the signal, say eleven rounds,`When its long tooth S1 willarrive in position for engagement with the pin 75; and a pin 90, \vhi'chis extended Alaterally from said tooth will engage the end of thebox-controller, as represented in F ig. 8,- and as the train continuesto run the box-controller Will be partially returned and thereafter'heldby the ratchet and pin in an intermediate position, .butJ still out ofelfective ield of the non-interference magnet.

Suchl artialreturn movement of the b cX- controler is sufficient to movethe pin 70 out of engaging'i'position With 'the tail of the ldoglpermitting movement of said dog, so that the pin 30 will thereafterengage.

, said dog, and thus connect the stopping-v means with the train., Saidstopping-means ivill be thencontinuously driven by the train, in regularmanner, for the sending of the delayed signal, which, however, may ormay not be sent, depending up'oii the condition of thecircuit, but atthe end of the predetermined number` of attempted rounds thelocking-member will enter the notch of the stop-wheel and stop thetrain, so that the delayed signal will not be sent.

Villiether or not the delayed signal is sent it will be observed thatlthe stopping-means will stop the train', and the counting-device isthereby ycaused to resume its normal position, the co-active relation ofits component parts becomingY disengaged. Hence Y Will be seen thataftermany attempts to send adelayed signal during an allotted period oftime, the signaling-train' is stopped, and' all of the component partsof the box caused to. resume their normal positions and long before thebox has exhausted its round capacity, so that the boX must not onlyl beagain pulled to send its signal, but that it.

' Will have ample capacity for sending each signal when so required. Y

During the many attempts to automatically commence `and send a delayedsignal it will be Lnoted that in case any attempt is successful., thecounting-device will act accordingly, tol count it outand then Will bereturned to Ynormalrvvhenev er the stopping- Ameans has been connectedWith the train and has been driven by the train for its fullV period oftime, and has resumed its normal position.

i Whenever the locking-lever is permitted to'resume 'its normal positionAthe pin 56 thereon Will engage the extension 55 on the signalekey, andwill restore and hold said key in its closed position so that the prop`canrpass beneath Ait to occupy a position to prevent said key openingwhen the boX is again pulled anduntil the signal-wheel has been advancedto engage the key.

As here shown, the armature and box-controller have associated Withthem. an improved form` of tension so constructed that as the armatureretracts the tension rapidly increases in leverage, whereby the armaturewill be held in retracted' position against attraction of its magneteven though the strength of the current varies considerably andincreases much ,beyond the y normal amount. Such arrangement insurescorrect Working of the non-interference devices even under greatvariation of current conditions of the circuit, which variations are ofadvantage at time' of signaling toincrease speed otcorrect signaling.This tension device consists of an arm 102,` attached to thelbox-controller land extended above its pivot for a considerabledistance, to the upper endportion of which one end of a link 103 isloosely connected, the other end of saidlink being connected to one endof a spring 104,

A.,and the other end of said spring being loosely connected to anadjusting-screw 105 much belowthe pivot.Y '-The line ot force o thetension when the armature is in attracted positionvis then near thepivotal point of the armature so that a small current will hold thearmature attracted.y Y y As the armature is retracted the uppei' end ofthe arm 102 carries the line of force of the'spring away fromv saidpivot and thereby-rapidly increases the leverage of said.

spring against attraction of the magnet, tending to hold the armatureretracted even lwhenfthe vmagnet is iniuenced by an` ex'- current.
